JRuby 安装失败，除非使用 "undefined local variable or method `r' for main:Object" 执行 sudo
JRuby installation failing unless sudo with "undefined local variable or method `r' for main:Object"
更新：当我使用 sudo（例如 sudo rbenv install jruby-9.1.2.0）时一切正常。但我不想要那个 :).
$ ruby -v
NameError: undefined local variable or method `v' for main:Object
<top> at -v:1
$ sudo ruby -v
jruby 9.1.2.0 (2.3.0) 2016-05-26 7357c8f Java HotSpot(TM) 64-Bit Server VM 25.51-b03 on 1.8.0_51-b16 +jit [darwin-x86_64]
正在寻找有关在安装过程中在哪里寻找需要什么东西的提示sudo。 C Ruby installs/runs 没有 sudo.
就好了
正在尝试安装 JRuby，但遇到 -r 标志被解释为变量的问题。使用 rvm 和 JRuby 1.7.x 版本时出现类似问题。同事没有任何相同的问题。以前能够使用 rvm 和 rbenv 安装 JRuby 1.7，但我不知道从那时起我的系统发生了什么变化。尝试将 JAVA_HOME 设置为 1.7 和 1.8 版本，结果相同。
我无法弄清楚我的系统是什么导致了这个问题——在重新映像之前寻找故障排除的想法:)。

jruby-launcher 也有问题，但不确定这是否只是一个症状：
$ gem install jruby-launcher
ERROR: Could not find a valid gem 'jruby-launcher' (>= 0) in any repository
ERROR: Possible alternatives: tmux_launcher, RubyRun_CE, ass_launcher, ec2launcher, jruby-ehcache
更新：出现在JRUBY_OPTS中使用-S选项是罪魁祸首。
我取消了用户会话中的所有环境变量设置，并确保 env 与 sudo env 完全匹配，但以下内容除外：
- 邮件
- 登录名
- 用户
- 用户名
- SUDO_COMMAND
- SUDO_USER
- SUDO_UID
- SUDO_GID
然后使用不带 sudo 的用户，我能够毫无问题地安装 JRuby。
现在，即使使用与我遇到问题时完全相同的环境变量，我现在也可以 install/execute JRuby 在闲暇时使用。仍然不知道为什么会这样，或者哪个环境变量有问题。
